Can not forge on Windows

Hi, I am getting this error while trying to launch server on my Atom machine. Any help? I am just average Windows user but would like to forge instead of selling.

"Java lang out of memory error: ran out of virtual memory on 32 bit jvm either use 64 bit jvm or reduce heap size".

Install 64 bit Java, you are using 32 bit one

When I try to install 64 bit version I am getting error that it might not work on my computer. Is it perhaps because I am using Atom computer? In Windows settings it says I have "32 bit system, processor x64".
